POWER KNEE is suitable for use in any environment except where spillage or immersion in water or any other fluid
is possible, or where exposure to highly electrical and/or magnetic fields can occur (e.g., electrical transformers,
high-power radio/TV transmitters, RF surgical equipment, CT and MRI scanners). The battery charger and power
supply are for indoor use only.
Make sure that no component of the prosthesis or accessories has been altered or tampered with.
Keep fingers away from the back side of the prosthesis joint to prevent the risk of pinching in the event of flexion.
Keep fingers away from the front side bumpers to prevent the risk of pinching during extension.
(Figure2)
Visually inspect the prosthesis before each use.
If you experience any problems with a component of the prosthesis or accessories that are not documented in this
manual, contact your Össur representative. Never attempt to make any technical repairs yourself.
Caution:
Avoid exposure to rain, snow, ice, or salt. Maintain and store in a clean and dry condition.
Caution:
Avoid exposure to intense dust or smoke or to excessive mechanical shocks or vibrations. Avoid impact to
the battery.
Caution:
Use the prosthesis at temperatures between –10°C and +40°C.
Caution:
Power on the prosthesis only when you are wearing it.
Caution:
Follow recommended maintenance intervals.
INDICATIONS FOR USE
The POWER KNEE is designed for patients with transfemoral and knee disarticulation amputation. The healthcare
practitioner must provide each patient with training for appropriate use and proper application of the system.
Limited to community and workplace ambulators with the ability or potential to traverse through most
environmental barriers such as curbs, stairs or uneven surfaces. Low to moderate impact only.
CONTRAINDICATIONS FOR USE
N/A.

PREPARATION FOR USE
CHECKING THE BATTERY STATUS (Figure 5)
Check the battery status on the battery at the front of the prosthesis. To check the battery status, press the battery
status button:
1. If five LEDs go on, the battery is fully charged.
2. If only the bottom LED goes on, the battery is nearly depleted and needs to be charged.
3. If no LED goes on, the battery is totally depleted and needs to be charged.
4. If five LEDs flash, the battery needs to undergo a
“self-maintenance”
process and needs to be charged.
5. If five LEDs go on in a wave-like pattern this indicates that self maintenance process will take place the next
time the battery is inserted into the charger. The LEDs will then indicate the battery status.
